Embodiment 1

[0029] The ilmenite flotation collector of the present embodiment is prepared from the following raw materials in percentage by weight: 4% ammonium dibutyl dithiophosphate, 45% sodium oleate, 23% diamine tetraacetic acid disodium salt , maleate 16%, water glass 1%, water 11%, weigh the raw materials according to the formula, add some water, mix and heat to 60°C to 80°C, stir for 0.5h-1.5h, this is component A , Add disodium edetate and maleate to the remaining water at 50°C-60°C, stir for 2h-4h, this is component B, after mixing component A and component B, add water glass After stirring evenly, the ilmenite flotation collector is prepared.

[0030] Using the prepared ilmenite flotation collector, the flotation grade is 20.42% of the raw ore, the titanium concentrate grade obtained is 48.21%, and the recovery rate is a good indicator of 81.91%.

Embodiment 2

[0032] The ilmenite flotation collector of the present embodiment is prepared from the following raw materials in percentage by weight: 4% ammonium dibutyl dithiophosphate, 47% sodium oleate, 21% disodium diaminetetraacetic acid , maleate 16%, water glass 1%, water 11%, weigh the raw materials according to the formula, add some water, mix and heat to 60°C to 80°C, stir for 0.5h-1.5h, this is component A , Add disodium edetate and maleate to the remaining water at 50°C-60°C, stir for 2h-4h, this is component B, after mixing component A and component B, add water glass After stirring evenly, the ilmenite flotation collector is prepared.

[0033] Using the prepared ilmenite flotation collector, the flotation grade is 20.42% of the raw ore, the titanium concentrate grade obtained is 48.54%, and the recovery rate is a good indicator of 82.33%.

Embodiment 3

[0035] The ilmenite flotation collector of the present embodiment is prepared from the following raw materials in percentage by weight: 4% ammonium dibutyl dithiophosphate, 49% sodium oleate, 19% disodium diaminetetraacetic acid , maleate 16%, water glass 1%, water 11%, weigh the raw materials according to the formula, add some water, mix and heat to 60°C to 80°C, stir for 0.5h-1.5h, this is component A , Add disodium edetate and maleate to the remaining water at 50°C-60°C, stir for 2h-4h, this is component B, after mixing component A and component B, add water glass After stirring evenly, the ilmenite flotation collector is prepared.

[0036] Using the prepared ilmenite flotation collector, the flotation grade is 20.42% of the raw ore, the titanium concentrate grade obtained is 48.66%, and the recovery rate is a good indicator of 82.67%.

Abstract

The invention discloses a flotation collecting agent, particularly relates to an ilmenite flotation collecting agent and a preparation method thereof, and belongs to the technical field of mineral flotation collecting. The ilmenite flotation collecting agent is prepared from the following raw materials: dibutyl ammonium dithiophosphate, sodium oleate, ethylenediamine tetraacetic acid disodium salt, maleate, water glass and the balance of water. The ilmenite flotation collecting agent is prepared by the following method: respectively weighing the raw materials according to the formula; adding part of water, performing heating to 60-80 DEG C after mixing, performing stirring for 0.5-1.5 hours to obtain a component A, adding the rest of water into disodium ethylene diamine tetraacetate and maleate at 50-60 DEG C, performing stirring for 2-4 hours to obtain a component B, mixing the component A and the component B, adding water glass, and performing uniform stirring to obtain the ilmeniteflotation collector. The ilmenite flotation collecting agent is low in cost, safe and environmentally friendly while the beneficiation effect of ilmenite is effectively guaranteed, and the fine gradeof ilmenite can be effectively improved after all the components cooperate with one another.

Description

technical field [0001] The invention relates to a flotation collector, in particular to an ilmenite flotation collector and a preparation method thereof, and belongs to the technical field of mineral flotation collectors. Background technique [0002] Flotation is a method of processing minerals by utilizing the difference between hydrophobicity and hydrophilicity on the surface of minerals. The process of separating mineral particles by using the physical and chemical properties of the mineral surface, formerly known as flotation beneficiation, is the most widely used beneficiation method. Almost all ores can be sorted by flotation. Such as gold, silver, galena, sphalerite, chalcopyrite, chalcocite, molybdenite, pentlandite and other sulfide minerals, malachite, white lead ore, smithsonite, hemimorphite and Separation of oxide minerals such as hematite, cassiterite, wolframite, ilmenite, beryl, spodumene, rare earth metal minerals, and uranium ore. Graphite, sulfur, diam...
